BIOLOGY 2 EXAM 1: PALMTAG FGCU ACTUAL 2025/2026
QUESTIONS AND 100% CORRECT ANSWERS
What is referred to as the "changing factor" in a scientific experiment?
independent variable
When the sixth step of the scientific method is referred to as "discussion" what is the term
discussion referring to?
when a scientist discussed weather or not the data from their experiment supported their
hypothesis and the relationship to other relevant scientific studies
What is the function of DNA?
store and transmit genetic information
On what structures do we find DNA?
chromosomes
What is a genome?
The entire set of genetic material in an organism
,What is the difference between a gene and an allele?
Genes are DNA sections that code for specific proteins or functional RNA, playing a crucial part
in biological functions. Alleles, however, are variations of these genes, leading to diverse traits
such as eye color.
Diploid vs. Haploid
diploid is two sets of chromosomes and haploid is one set of chromosomes
What are homologous chromosomes?
Two chromosomes with the same set of genes, in the same sequence, sometimes with different
alleles
coding genes
code for unique protein molecules
noncoding genes
genes that are transcribed but not translated
What is the evolution?
the process of change over time. DESCENT WITH MODIFICATION
, descent with modification
principle that each living species has descended, with changes, from other species over time
Living things (populations) change over time + Natural selection =
Evolution
Point mutations are
changes in the base genes that can have a significant impact on phenotype; ex. sickle-cell
disease
Transcription vs. Translation
Transcription : DNA -> RNA
Translation : RNA -> Protein
artificial selection
Process of human directed breeding aimed to select traits that nature may not have otherwise
selected
natural selection
